Description

Dual-bearing fishing reel

Technical Field

The present invention relates to a dual-bearing reel, and more particularly, to a dual-bearing reel having a clutch mechanism for coupling a handle and a spool and releasing the coupling of the handle and the spool.

Background

In a dual-bearing reel, a clutch mechanism is provided between a handle and a spool (see, for example, patent document 1). The clutch mechanism connects the handle and the spool and releases the connection therebetween. The clutch mechanism has a clutch fork (clutch yoke) and a strut member supporting the clutch fork.

For example, in the stay member of patent document 1, two stay portions and a main body portion to be attached to a frame are integrally formed. In patent document 2, two strut members are directly attached to a frame. These strut members are generally made of metal because they need to support a clutch fork that moves a pinion (pinion gear) receiving a load in the axial direction of the spool.

Disclosure of Invention

[ technical problem to be solved by the invention ]

In the conventional dual-bearing reel, when water, salt water, or the like adheres to the metal stay member, the stay member may be corroded. Here, when the metal pillar member is corroded, the strength and shape of the pillar member are damaged. Further, the stay member and the clutch fork are adhered to each other by precipitated salt, or the surface roughness of the stay member is increased. That is, the strut member in the related art may not properly guide the clutch fork in the axial direction.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a dual-bearing reel capable of appropriately guiding a clutch fork.

[ technical means for solving problems ]

A dual-bearing reel according to an aspect of the present invention includes a clutch mechanism that couples a handle and a spool and releases the coupling of the handle and the spool. The dual-bearing reel includes a metal frame, a clutch fork, and a resin guide member.

The metal frame supports a handle shaft of the handle. The clutch fork is a member for switching the clutch mechanism between a connected state and a disconnected state. The resin guide member includes: a main body portion attached to the frame; and a support portion formed integrally with the main body portion and guiding the clutch fork in an axial direction.

In the dual-bearing reel, the support portion is made of resin, and therefore, the support portion can be prevented from being corroded. That is, in the dual-bearing reel, since the deformation of the support portion and the reduction in strength of the support portion due to corrosion do not occur, the clutch fork can be appropriately guided by the support portion. In addition, adhesion of the support portion and the clutch fork due to the precipitates and an increase in surface roughness of the support portion can be prevented, so that the clutch fork can be properly guided by the support portion.

In addition, in the dual-bearing reel, the main body portion is made of resin, and therefore, the main body portion can be prevented from being corroded. Accordingly, the posture of the support portion does not change due to corrosion of the body portion, and therefore the clutch fork can be guided more appropriately by the support portion.

In the dual-bearing reel according to another aspect of the present invention, the support portion includes a guide shaft. The guide shaft protrudes from the main body. At least a part of the guide shaft is formed in a substantially cylindrical shape. In this case, the reinforcing member is disposed on the inner peripheral portion of the guide shaft.

In this configuration, since the reinforcing member is disposed on the inner peripheral portion of the guide shaft, the strength of the guide shaft can be increased. Accordingly, the clutch fork can be appropriately guided by the support portion (guide shaft).

In the dual-bearing reel according to another aspect of the present invention, the reinforcing member is preferably made of metal. According to this configuration, the strength of the protruding portion can be further increased, and the clutch fork can be appropriately guided by the support portion (protruding portion).

The dual-bearing reel according to another aspect of the present invention further includes a clutch cam (clutch cam) that moves the clutch fork in the axial direction. The main body portion is disposed between the frame and the clutch cam.

With this configuration, the clutch fork can be appropriately guided by the support portion (projecting portion).

[ Effect of the invention ]

In the dual-bearing reel of the present invention, the clutch fork can be appropriately guided.

Detailed Description

As shown in fig. 1, a dual-bearing reel 1 according to an embodiment of the present invention includes a reel unit 3 attachable to a fishing rod, a handle 4 for rotation of a spool disposed on a side of the reel unit 3, and a spool 7 (see fig. 2) rotatably attached to the reel unit 3. As shown in fig. 2, the dual-bearing reel 1 further includes a clutch mechanism 25, and the clutch mechanism 25 can couple the handle 4 and the spool 7 and can release the coupling of the handle 4 and the spool 7.

In the following, the rotation center axis of the spool 7 is referred to as a spool axis X. The direction in which the bobbin axis X extends and the direction along the bobbin axis X are referred to as the bobbin axial direction, and the direction around the bobbin axis X with the bobbin axis X as the center is referred to as the circumferential direction (rotation direction). The direction away from the axis X of the spool with the axis X of the spool as the center is also referred to as the radial direction.

Fishing reel unit

As shown in fig. 2, the reel unit 3 includes: a metal frame 5; a first side cover 6a and a second side cover 6b installed in such a manner as to cover both sides of the frame 5; and a front cover 8 (see fig. 1) attached to the front of the frame 5.

The frame 5 has a first side plate 9a and a second side plate 9b which are disposed to face each other with a space therebetween. The first side plate 9a and the second side plate 9b are coupled by a coupling portion 9 c.

The first side plate 9a has a first opening 9d. A bearing housing 16 is fixed to the first opening 9d. A clutch control device 30 described later is attached to the second side plate 9b. The second side plate 9b has a second opening 9e through which the spool shaft 15 passes. The first side cover 6a is attached to the first side plate 9a of the frame 5. The second side cover 6b is attached to the second side plate 9b of the frame 5.

As shown in fig. 3, the spool 7 and the clutch operating member 11 are disposed on the frame 5, for example, between the first side plate 9a and the second side plate 9b. Further, between the frame 5 and the second side cover 6b, for example, a rotation transmission mechanism 13 and a clutch control device 30, which will be described later, are disposed. That is, the dual-bearing reel 1 further includes a clutch operating member 11, a rotation transmission mechanism 13, and a clutch control device 30.

< reel >

As shown in fig. 2 and 3, the spool 7 is rotatably disposed between the first side plate 9a and the second side plate 9b. The spool 7 is fixed to the spool shaft 15 so as to be rotatable integrally with the spool shaft 15.

The spool shaft 15 is configured to be rotatable with respect to the reel unit 3. For example, as shown in fig. 2, one end of the spool shaft 15 is rotatably supported by the first side plate 9a via a bearing 16a disposed in the bearing housing 16. The other end portion of the spool shaft 15 is rotatably supported by the second side plate 9b via a bearing 16 b. An engagement pin 15a constituting a clutch mechanism 25 is attached to the spool shaft 15.

< Clutch operating Member >

As shown in fig. 1 and 3, the clutch operating member 11 is disposed at the rear of the reel unit 3. The clutch operating member 11 is coupled to the clutch control device 30. The clutch operating member 11 is configured to be movable between a clutch engagement position (see a solid line in fig. 1) and a clutch disengagement position (see a broken line in fig. 1). The clutch operating member 11 also serves as a thumb rest when a thumb-controlled spool paying out (thumb) operation is performed.

< rotation transmitting mechanism >

The rotation transmission mechanism 13 is used to transmit the rotational force from the handle 4 to the spool 7. As shown in fig. 3, for example, the rotation transmission mechanism 13 includes a handle shaft 17, a drag mechanism 19, a drive gear 21, and a pinion gear 23 (see fig. 2).

The handle 4 is attached to the handle shaft 17. The handle shaft 17 is rotatably supported by the metal frame 5. Specifically, the handle shaft 17 is rotatably supported by the second side cover 6b and the frame 5. For example, the handle shaft 17 is rotatably supported by the second side cover 6b via a one-way clutch (not shown) that prohibits rotation in the wire feeding direction. The handle shaft 17 is rotatably supported by the second side plate 9b via a bearing (not shown).

The drag mechanism 19 transmits the rotation of the handle shaft 17 to the drive gear 21, and brakes the rotation of the spool 7 at the time of unwinding. As shown in fig. 3, the drag mechanism 19 is disposed between the handle shaft 17 and the drive gear 21.

The drive gear 21 is rotatably attached to the handle shaft 17. As shown in fig. 3, the rotation of the handle shaft 17 is transmitted to the drive gear 21 via the drag mechanism 19. Here, the drive gear 21 is a helical gear. When a torque equal to or greater than a predetermined value is applied to the spool 7 during unwinding, the drag mechanism 19 operates to rotate the drive gear 21 with respect to the handle shaft 17.

The pinion gear 23 transmits the rotation of the drive gear 21 to the spool shaft 15. As shown in fig. 2 and 3, the pinion gear 23 is formed in a substantially cylindrical shape and is disposed on the outer peripheral side of the spool shaft 15.

As shown in fig. 2, the pinion 23 has a helical tooth portion 23a, an engagement groove 23b, and a small diameter portion 23c. The tooth portion 23a meshes with the drive gear 21.

The engagement groove 23b is formed at an end of the pinion 23 and extends in the radial direction. The outer peripheral surface of the cylindrical portion in which the engagement groove 23b is formed is rotatably supported by a guide member 45 (described later) via a bearing 24 (see fig. 2). The small diameter portion 23c is formed between the tooth portion 23a and the engagement groove 23 b. The clutch fork 41 (described later) is engaged with the small diameter portion 23c.

< Clutch mechanism >

The clutch mechanism 25 is configured to be able to connect the handle 4 and the spool 7 and to release the connection between the handle 4 and the spool 7. As shown in fig. 2, the clutch mechanism 25 includes an engagement groove 23b of the pinion 23 and an engagement pin 15a of the spool shaft 15.

For example, when the pinion 23 moves in a direction away from the spool 7 along the spool shaft 15 and releases the engagement of the engagement groove 23b and the engagement pin 15a of the spool shaft 15, the clutch disengaged state (coupling released state) is established. In this case, the spool 7 can freely rotate.

On the other hand, when the pinion 23 moves along the spool shaft 15 in a direction approaching the spool 7 and the engagement groove 23b engages with the engagement pin 15a, the clutch engaged state (connected state) is established. In this case, the spool 7 rotates in conjunction with the rotation of the handle shaft 17.

< Clutch control device >

The clutch control device 30 is configured to be able to control the clutch mechanism 25 in accordance with the operation of the clutch operating member 11. As shown in fig. 3, the clutch control device 30 includes a clutch fork 41, a clutch cam 43, and a guide member 45 made of resin.

(Clutch fork)

The clutch fork 41 is a member for switching the clutch mechanism 25 between a clutch engaged state and a clutch disengaged state. As shown in fig. 3, the clutch fork 41 is guided in the spool axial direction by the clutch cam 43 and the guide member 45.

As shown in fig. 2, the clutch fork 41 includes an engagement recess 41a engageable with the pinion gear 23 and a pair of guide holes 41b. The engagement recess 41a engages with the small diameter portion 23c of the pinion 23.

The pair of guide holes 41b penetrate the clutch yoke 41 in the spool axial direction. Guide shafts 48 (described later) are inserted through the guide holes 41b. Both end portions of the clutch fork 41 are engaged with the clutch cam 43.

(Clutch cam)

The clutch cam 43 is a member for moving the clutch fork 41 in the spool axial direction. The clutch cam 43 is disposed on the guide member 45 so as to be rotatable about the bobbin axis X.

The coupling member 42 is attached to the clutch cam 43. The coupling member 42 couples the clutch operating member 11 and the clutch cam 43. When the clutch operating member 11 is operated, the clutch cam 43 rotates via the coupling member 42.

The clutch cam 43 is disposed on the outer peripheral side of a second cylindrical portion 46c (described later) of the guide member 45 and is rotatable around the second cylindrical portion 46c. The clutch cam 43 is positioned in the axial direction by the positioning member 50. The positioning member 50 is fixed to the second side plate 9b by a fixing member, for example, a screw member 50 a.

The clutch cam 43 has a cam portion 43a for guiding the clutch fork 41 in the axial direction. When the clutch cam 43 is rotated by the operation of the clutch operating member 11, the cam portion 43a presses both end portions of the clutch fork 41. Then, both end portions of the clutch fork 41 move in a direction away from the spool 7 in the spool axial direction. Accordingly, the clutch mechanism 25 can be switched from the clutch engaged state to the clutch disengaged state.

On the other hand, when the clutch return mechanism (not shown) is operated by the operation of the handle 4, the clutch cam 43 rotates in the direction opposite to the above-described rotation direction. Then, both end portions of the clutch fork 41 move in the direction approaching the spool 7 in the spool axial direction. Accordingly, the clutch mechanism 25 can be switched from the clutch disengaged state to the clutch engaged state.

(guide member)

The guide member 45 guides the clutch fork 41 in the spool axial direction. As shown in fig. 3, the guide member 45 is attached to the frame 5. As shown in fig. 4 and 5, the guide member 45 includes a body portion 46 and a guide portion 47 (an example of a support portion). The guide member 45 further includes a reinforcing member 49 (see fig. 5).

As shown in fig. 3, the main body 46 is attached to the frame 5. As shown in fig. 4 and 5, the main body portion 46 has a fixing portion 46a, a first cylindrical portion 46b, and a second cylindrical portion 46c.

The fixing portion 46a is formed in a substantially plate shape. The fixing portion 46a is disposed between the frame 5 and the clutch cam 43. The fixing portion 46a is fixed to the frame 5, for example, the second side plate 9b, by a fixing mechanism, for example, a screw member 51 (see fig. 3).

The first cylindrical portion 46b is formed integrally with the fixing portion 46 a. The first cylindrical portion 46b penetrates the fixing portion 46a in the spool axial direction, and protrudes from the fixing portion 46 a. The first cylindrical portion 46b is disposed in the second opening 9e (see fig. 2) provided in the second side plate 9b. The spool shaft 15 is disposed on the inner peripheral side of the first cylindrical portion 46 b.

The second cylindrical portion 46c is formed integrally with the fixed portion 46 a. The second cylindrical portion 46c is circumferentially coupled to a pair of guide shafts 48 (described later). A clutch cam 43 (see fig. 3) is disposed on an outer peripheral portion of the second cylindrical portion 46c.

As shown in fig. 5, the inner diameter of the second cylindrical portion 46c is larger than the inner diameter of the first cylindrical portion 46 b. A bearing 24 (see fig. 2) for supporting the pinion gear 23 is disposed on an annular step portion 46d formed by the first cylindrical portion 46b and the second cylindrical portion 46c.

As shown in fig. 4 and 5, the guide portion 47 is formed integrally with the body portion 46. The guide portion 47 guides the clutch fork 41 in the spool axial direction. The guide section 47 has a pair of guide shafts 48 (one example of at least two projecting sections) projecting from the body section 46.

The pair of guide shafts 48 is formed integrally with the main body 46, for example, the fixing portion 46 a. The pair of guide shafts 48 project from the fixing portion 46a in the axial direction of the spool. The pair of guide shafts 48 are disposed at intervals in the circumferential direction.

The pair of guide shafts 48 is inserted through the pair of guide holes 41b of the clutch fork 41. In this state, the coil spring 44 is disposed on the outer periphery of each guide shaft 48 (see fig. 2). For example, the coil spring 44 is disposed on the outer periphery of each guide shaft 48 in a state of being compressed between the clutch fork 41 and the second side cover 6b.

For example, when the clutch mechanism 25 is in the clutch engaged state, when the clutch cam 43 is rotated by the operation of the clutch operating member 11, the clutch fork 41 is guided by the pair of guide shafts 48 and moved in a direction away from the spool 7 in the spool axial direction. Accordingly, the clutch mechanism 25 can be switched from the clutch engaged state to the clutch disengaged state.

On the other hand, when the clutch return mechanism (not shown) is operated by the operation of the handle 4, the clutch fork 41 is urged by the coil spring 44 and moves in the spool axial direction toward the spool 7 along the pair of guide shafts 48. Accordingly, the clutch mechanism 25 can be returned from the clutch disengaged state to the clutch engaged state.

Next, the structure of the guide shaft 48 will be described in detail. As shown in fig. 5, at least a part of the guide shaft 48 is formed in a substantially cylindrical shape. A reinforcing member 49 is disposed on the inner peripheral portion of the guide shaft 48.

Here, a part of the guide shaft 48 is formed in a substantially cylindrical shape. The guide shaft 48 has a hollow first shaft portion 48a and a solid second shaft portion 48b. The first shaft portion 48a is formed integrally with the fixing portion 46a, and projects from the fixing portion 46a in the axial direction of the spool. The base end of the first shaft 48a corresponds to the base end of the guide shaft 48.

The first shaft portion 48a is formed in a substantially cylindrical shape. A reinforcing member 49 is disposed in a hole 48c, which is an inner peripheral portion of the first shaft portion 48 a. The hole 48c of the first shaft 48a opens on the second side plate 9b side of the frame 5.

The second shaft portion 48b is formed integrally with the first shaft portion 48 a. The second shaft portion 48b extends from the tip end portion of the first shaft portion 48a in the spool axial direction. The distal end of the second shaft 48b corresponds to the distal end of the guide shaft 48. The second shaft portion 48b is formed in a solid rod shape.

The reinforcing member 49 is a member for reinforcing the strength and rigidity of the guide shaft 48. The reinforcing member 49 is made of metal. The reinforcing member 49 is, for example, a metal pin member.

The reinforcing member 49 is disposed on the inner peripheral portion of the guide shaft 48 on the base end side of the guide shaft 48. The reinforcing member 49 is fitted in the hole portion 48c of the first shaft portion 48 a. Specifically, the reinforcing member 49 is fitted from the second side plate 9b side of the frame 5 toward the hole portion 48c of the first shaft portion 48 a. Accordingly, when the guide member 45 is attached to the second side plate 9b of the frame 5, the hole portion 48c of the first shaft portion 48a and the reinforcing member 49 are covered by the second side plate 9b. Therefore, even if the reinforcing member 49 is made of metal, adhesion of water, brine, or the like can be prevented.

Here, the length L1 of the reinforcement member 49 in the axial direction is longer than an axial distance L2, and the axial distance L2 is a distance between the facing surface S1 of the fixing portion 46a facing the second side plate 9b and the contact surface S2 of the clutch cam 43 in the clutch engaged state and contacting the clutch fork 41. Accordingly, the fixed end side of the guide shaft 48 can be reliably reinforced by the reinforcing member 49.

In the dual-bearing reel 1 described above, since the guide member 45 (the main body portion 46 and the guide portion 47) is made of resin, the guide portion 47 can be prevented from being corroded. That is, in the dual-bearing reel 1, since the guide portion 47 is not deformed by corrosion and the strength of the guide portion 47 is not reduced by corrosion, the clutch fork 41 can be guided well by the guide portion 47. In addition, adhesion of the guide portion 47 and the clutch fork 41 and an increase in surface roughness of the guide portion 47 can be prevented, so that the clutch fork 41 can be properly guided by the guide portion 47.

In addition, in the dual-bearing reel 1, since the guide portion 47 is formed integrally with the body 46, it is not necessary to use a metal fixing member for fixing the guide portion 47 to the body 46 as in the conventional art. That is, in the dual-bearing reel 1, since the posture of the guide portion 47 does not change due to corrosion of the metal fixing member, the clutch fork 41 can be more appropriately guided by the guide portion 47.

In the dual-bearing reel 1, the reinforcing member 49 is disposed on the inner peripheral portion of the guide shaft 48, and therefore, the strength of the guide shaft 48 can be increased. Accordingly, the clutch fork 41 can be appropriately guided by the guide shaft 48.
